A passenger on a flight from Houston to Washington D.C. has accused United Airlines of giving her first-class seat to U.S. Rep. Sheila Jackson Lee. D-Houston, and then threatening to remove her from the plane for complaining and snapping a photo of the Houston congresswoman.

“It was just so completely humiliating,” said Jean-Marie Simon, a 63-year-old attorney and private school teacher who used 140,000 miles on Dec. 3 to purchase the first-class tickets to take her from Washington D.C. to Guatemala and back home.

When it came time to board the last leg of her flight home from George Bush Intercontinental Airport on Dec. 18, after a roughly hour-long weather delay, Simon said the gate attendant scanned her paper ticket and told her it was not in the system.

Did you cancel your flight?, the attendant asked.

“No,” she said she replied. “I just want to go home.”

Her seat, 1A, was taken, she was told. Simon was given a $500 voucher and reseated in row 11, Economy Plus.

Simon later learned that Jackson Lee was in her pre-purchased seat and has alleged that the congresswoman received preferential treatment, which United denies.

Sheila Jackson Lee (D-Texas) in seat 1A the one I paid for dearly, and the one United gave to her without my consent or knowledge! Fellow congressman on same flight said she does it repeatedly. @unitedpic.twitter.com/Q2c6u6B0Yp

Rep. Sheila Jackson Lee was silenced during Attorney General Jeff Sessions’ Tuesday testimony when she refused to let him answer a question.

During a House Judiciary Hearing with Sessions, Jackson Lee asked the AG if he stood by his previous testimony in front of the Senate Intelligence Committee. The Democratic lawmaker’s awkwardly phrased and roundabout question required Sessions to ask her to repeat it several times.

Sessions earlier testified that the “chaos” of Trump’s campaign was responsible for him forgetting about a meeting in which Trump campaign aide George Papadopoulos had floated using his contacts within the Russian government to set up a direct meeting between Trump and Russian President Vladimir Putin.

In response to Lee’s questioning, Sessions again insisted that he would have told the Senate about the Papadopoulos meeting if he had recalled it because the record shows that he had pushed back on the campaign aide’s plan to set up a Trump-Putin meeting.

“I had not recalled that meeting when that occurred,” he said. “But I would have been pleased to have responded and explained it if I recalled it.”
